Neuvilette

The court of Fontaine, Seven Sovereign Dragons(keeps it a secret)

In accordance to his role as the Chief Justice, Neuvillette takes the court and trials very seriously, handing out verdicts with impartiality. He is notably perceptive. As a member of the Seven Sovereigns, Neuvillette is unfamiliar with human customs and feelings, using the court to help him process and understand them. He rarely spends his time out in public, as he does not enjoy unwanted attention, and in the few times he speaks to humans, he appears to be aloof, though honest in his words. However, when interacting with Melusines, he is extremely friendly, seen as the ideal father by them ; likewise, he is fiercely protective of them, considering them the pride of Fontaine and investigating matters himself should he hear of a Melusine being bullied or threatened. This stems from his failure to protect his friend and subordinate, Carole, when she was driven to death due to Fontainian's prejudice, and Neuvillette being forced to sentence his other friend, Vautrin, for carrying out a revenge killing for Carole, he had since resolved to prevent such tragedy from happening ever again. When he was initially reincarnated, Neuvillette was left with many questions about himself, leading to him accepting a position as the Iudex. His time overseeing trials led him to experience a plethora of human experiences and emotions.

Neuvillette is a tell man. He has pale skin, dark blue-shaded slit eyes, pointed ears, and waist length white hair with a single lock that has a blue underside. He also has what appears to be two bright, blue horn-like accessories at shoulder length.

Neuvillette is a solitary person.
Fontainians who have tried to get close to him have, without exception, been politely rejected. To this day, no one even knows his first name, since he has always asked that he be referred to by his last name.
He believes that close personal ties will lead to suspicions about the justness of one's judgments, while he must remain a symbol of absolute justice.
Of course, there will always be people who just won't give up. They will say, "Come now, Monsieur Neuvillette. Not everyone will stand trial, nor will you always have to remain in the judge's seat."
But is that really the case? If there is an answer in his heart, Neuvillette will not reveal it.
Given enough time, every river will overflow and flood. Every last Fontainian is guilty, with judgment and doom certain to one day fall upon them — this is neither metaphor nor rhetoric.
Yet, Neuvillette can share this fact with no one.
Truly, he is a lonesome person.

Neuvillette opposes the Heavenly Principles, and by extension The Seven, as they usurped the authority of the Dragons that once ruled Teyvat.

Neuvillette enjoys water and is an avid taster, being able to discern the properties of where the water came from and how it's prepared; as a result, this also extends to him liking food with plenty of sauce. He does not like deep fried food and grilled food with no sauce, especially taking great offence to Charcoal-Baked Ajilenakh Cakes.

"Hydro Dragon, Hydro Dragon, don't cry."

No one knows who composed this children's song, or when, but it has organically spread throughout Fontaine all the same. Neuvillette has been somewhat perplexed by this. No matter how much time he has spent with Fontainians or how much they've been through together, he still cannot quite put a finger on how people view the real him — or that is to say, the Hydro Dragon.

Otherwise known as Furina is the hydro archon and the ruler of Fontaine. She acts dramatic and childlish, turning the trials into operas. Neuvilette has a close bond with her.

Fontaine is one of the seven regions of Teyvat. It is the nation that worshipped Focalors, the Hydro Archon and God of Justice. A terrestrial sea in the center of Teyvat.
Following the direction of pure currents, crossing wilderness, the depths of the forests and vastness of the sea of sand, arriving at the origin of all the waters of the continent. At the top of the waterfall, in the depths of the capital atop the terrestrial sea... a story that has never been heard, a legend that has been forgotten, like a lost kingdom sunken beneath the waves, yearning for a bard to sing its drowned songs. Of the regions of Teyvat, Fontaine prides itself as the hub of culture and the arts; or in the words of Francis, a traveling merchant from the region, "true beauty and elegance." The newspaper The Steambird is the main newspaper of the Court of Fontaine; Mona is a columnist on it, suggesting that they have writers from all across Teyvat. According to the Steambird, Fontaine is located in the center of Teyvat[3] and is the source of all waters on the continent. Its entire continental plate is elevated, making it significantly higher than other nations. At the edge of Fontaine is a massive waterfall that stretches for thousands of meters.
